The song "Rock Island Line" tells the story of a train journey on the Rock Island Line that runs into New Orleans. The song highlights the practice of toll gates where passengers have to pay a fee to pass through. However, if the train is carrying certain goods or livestock, the fee is waived. In the lyrics, the train arrives at the toll gate, and the conductor informs the toll gate man about the various livestock on board, including pigs, horses, cows, and sheep. The toll gate man allows the train to pass without payment since it is carrying livestock. Once the train is out of sight, the conductor tricks the toll gate man, revealing that the train is actually carrying pig iron instead of livestock. The conductor proudly declares his victory, stating, "I fooled you!" The song emphasizes the significance and greatness of the Rock Island Line as a good road to travel. It encourages listeners to ride the Rock Island Line as they find it. The meaning behind "ride her like you find her" suggests making the most of the opportunities and experiences the journey has to offer. Overall, the song portrays an amusing story of deception and pays tribute to the Rock Island Line as a mighty good road to ride.
